Abstract

On three occasions – Denmark on the Maastricht Treaty, Ireland on the Nice Treaty and Ireland again on the Lisbon Treaty – voters have initially rejected an EU treaty only to vote in favour of it in a second referendum. Based on research conducted in Denmark and Ireland, Ece Özlem Atikcan assesses the reasons why voters changed their minds in each case. She illustrates that ‘Yes’ campaigners in both states learned from previous referendums and developed an approach that reframed the issue by emphasising concessions gained from the EU and the risks of rejecting a treaty for a second time.
